| Name | Type | Description |
| vi | ViSession | Identifies your instrument session. The ViSession handle is obtained from the niRFSG_init function or the niRFSG_InitWithOptions function and identifies a particular instrument session. |
| source | ViConstString | Specifies the source terminal for the digital edge trigger. NI-RFSG sets the NIRFSG_ATTR_DIGITAL_EDGE_START_TRIGGER_SOURCE attribute to this value. |
| edge | ViInt32 | Specifies the active edge for the Start Trigger. NI-RFSG sets the NIRFSG_ATTR_DIGITAL_EDGE_START_TRIGGER_EDGE attribute to this value. |
